Language & WorldFact
Japanese mixes three scripts in a single sentence.
A Japanese sentence combines kanji (Chinese characters for word stems, about 2,100 in the school list), hiragana (46 syllable signs for endings and grammar) and katakana (46 signs for loanwords and emphasis). 'I drink coffee' uses all three: 私はコーヒーを飲む. Add rōmaji, our alphabet, for abbreviations and brands.
Useful: Katakana flags loanwords: コーヒー is 'kōhī', i.e. coffee.
